Struct abstract_ns::WeightedSet

pub struct WeightedSet<'a> { /* fields omitted */ }

A structure that represents a set of addresses of the same priority

Methods

impl<'a> WeightedSet<'a>

fn pick_one(&self) -> Option<SocketAddr>

Select one random address to connect to

This function selects a host according to the random distribution according to the weights.

Returns None if the set is empty

fn addresses(&self) -> AddressIter

Returns iterator over underlying addresses

This effectively discards weights, but may be useful for cases where you treat addresses as a set. For example to find out whether two Address values intersect over SocketAddr.

fn compare_addresses(
    &self,
    other: &WeightedSet
) -> (Vec<SocketAddr>, Vec<SocketAddr>)

Compares two weighted sets to find out which addresses have been removed from set or added

This doesn't compare weights of the addresses

Trait Implementations

impl<'a> PartialEq for WeightedSet<'a>

fn eq(&self, other: &WeightedSet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
